When you shoot with the Lux Senior, you hold the fusion of vintage style with future technology in your hands. A unique flash bulb The closed device is the size of a medium-sized phone that you always carry with you. When you open it, however, it transforms into a time machine that takes you on a journey through the history of photography, offering special lighting effects. Simplicity The Lux Senior has two light control modes: automatic and manual. You can choose A mode to forget about settings and focus solely on your shots, or M mode to have full control over exposure.
